# Terms of use

> The terms for using the Canvas64 interface: the site, the docs, the API and the MCP server.

Last updated: 16 October 2026.

These terms govern your use of the Canvas64 interface: the website, these docs, the API and the MCP server (together, **the interface**). The interface is one way to read and use the Canvas64 smart contract on Base at `0x99Ff41906550F0C0F3EC66a11525e38C548e5011` (**the contract**). The contract is software that runs on a public blockchain, by itself, under the rules written in its code; it is not operated by the people who publish the interface (**we**, **us**). By using the interface you accept these terms, [Before you buy](https://canvas64.com/docs/risks.md), the [privacy policy](https://canvas64.com/docs/privacy.md), the [content policy](https://canvas64.com/docs/content-policy.md) and the [copyright policy](https://canvas64.com/docs/copyright.md), which form part of them. If you do not accept them, do not use the interface.

## 1. The interface and the contract

1.1 The interface displays public data from the blockchain and helps you prepare transactions that your own wallet signs and sends. We are not a party to any transaction between you, the contract or other users, and we do not broker, execute, clear or settle anything.

1.2 The contract has no owner and cannot be upgraded. Within its code, the only powers anyone holds are those described on [the rules page](https://canvas64.com/rules): to pause new sales for an emergency, seven days at a time, and to change the address that receives the platform's share. Nobody can change a price, a rate or an owner, take a cell, or move anyone's funds.

1.3 The contract can be used without the interface, through any other software that can call it. These terms cover the interface only.

## 2. Eligibility

2.1 You may use the interface only if you have reached the age of majority where you live, can enter into these terms, and are allowed to use it under the laws that apply to you.

2.2 You may not use the interface if you are the subject of sanctions or are acting for, or on behalf of, anyone who is, or if you are located in a place where using it would be unlawful.

2.3 You are solely responsible for knowing and following the laws that apply to you, including on digital assets, advertising and taxes. We may restrict or block access to the interface from any place, or for any person, at our discretion.

## 3. Your wallet

3.1 There are no accounts. You connect a wallet you control, and every transaction and message is signed by it. We never receive, hold or control your private keys, recovery phrase or funds.

3.2 You are solely responsible for the security of your wallet and for every transaction and message it signs. Transactions on a blockchain are final and cannot be reversed, refunded or cancelled by anyone. A wallet whose recovery phrase is lost cannot be restored by anyone.

3.3 We owe you no fiduciary duty and act as no agent, broker, custodian or adviser.

## 4. Cells

4.1 A cell is a position recorded by the contract: the right, under the contract's rules, to have your profile shown in that place of the wall on the interface until the cell is bought out. The contract assigns a cell to the wallet that last bought it.

4.2 Anyone can buy any cell at its next step, and its owner cannot refuse. The prices, the payouts, the royalties and the 2% fee are fixed by the contract and paid by it, in the transaction of each sale, to the addresses it holds.

4.3 A cell is not a security, a share, a deposit, a loan, a partnership interest or a claim against us or anyone else. Buying a cell gives you no right to profits from our efforts or anyone's, no voting or ownership right in any business, and no claim against anyone but what the contract's code itself does.

4.4 What a cell pays depends only on the contract's rules and on the independent decisions of other people to buy it. We make no promise and no representation that any cell will be bought, at any price or at any time, or that it will hold or gain any value.

## 5. Fees and taxes

5.1 Network fees are charged by the blockchain, not by us, and are not refundable. The platform's share is set by the contract.

5.2 You are solely responsible for determining, reporting and paying any taxes on what you pay and receive.

## 6. Risks

You accept the risks of using a blockchain, a stablecoin and a smart contract, including those described in [Before you buy](https://canvas64.com/docs/risks.md): among them, that the contract's audit is still to come, that networks and stablecoins can fail, freeze or change, that wallets can be lost or stolen, and that laws can change. You use the interface and the contract at your own risk.

## 7. What you put on the wall

7.1 You keep the rights you hold in your name, photo and links. You grant us a worldwide, royalty-free, non-exclusive licence to host, copy, display and adapt them, in the interface, in previews and shares of the wall and of your cell, and in material that shows the wall, for as long as they are on your profile and afterwards in archives and material already made.

7.2 You promise that you hold every right needed to post them, that they are lawful, and that they follow the [content policy](https://canvas64.com/docs/content-policy.md).

7.3 We may screen, refuse, hide or remove any content on the interface at our sole discretion, with or without notice, and we have no duty to monitor it. Hiding content on the interface does not affect a cell or what it earns under the contract.

## 8. What you may not do

You may not use the interface to: break any law or anyone's rights; evade sanctions or launder money; engage in unlawful market manipulation; impersonate anyone or imply an endorsement; defraud, phish or mislead; post content the content policy forbids; scrape it beyond what its public API and MCP server offer; attack, overload, probe or reverse-engineer it beyond normal use; or get around screening, reports, rate limits or access restrictions.

## 9. Third-party services

The interface works with services we do not control: wallets, WalletConnect, blockchain networks and their nodes, the USDC stablecoin and its issuer, hosting, and the services your links point to. Their terms apply to your use of them, and we are not responsible for them, their availability or their content.

## 10. Our marks

The Canvas64 name, the mark and the interface's design belong to us. Public data from the contract belongs to no one and can be read freely. Other brands' marks shown on the interface belong to their owners and are used only to name their services.

## 11. Changes, suspension and access

The interface is provided as it is and as available. We may change, suspend or discontinue any part of it, or restrict anyone's access to it, at any time and without notice or liability. The contract is not affected and keeps working.

## 12. No advice

Nothing on the interface or in these docs is financial, investment, legal, tax or other advice. Figures shown are what the contract's rules produce at each step, not forecasts or offers.

## 13. Disclaimer of warranties

To the fullest extent permitted by law, the interface, the docs, the API, the MCP server and any information in them are provided without warranties of any kind, express or implied, including of merchantability, fitness for a purpose, title, accuracy, availability and non-infringement. We do not warrant that the contract or the interface is free of errors, vulnerabilities or interruptions.

## 14. Limitation of liability

14.1 To the fullest extent permitted by law, we and everyone involved in publishing the interface shall not be liable for any indirect, incidental, special, consequential or exemplary damages, or for any loss of profits, revenue, data, tokens, goodwill or opportunity, arising from or related to the interface, the contract, any blockchain or stablecoin, any wallet, or the acts or omissions of any other person, however caused and even if foreseeable.

14.2 Where liability cannot be excluded, our total liability for all claims is limited to the lesser of the platform's share the contract received from your own purchases in the twelve months before the claim, and one hundred US dollars.

## 15. Indemnity

You will defend, indemnify and hold harmless us and everyone involved in publishing the interface against any claim, loss, liability, cost or expense, including reasonable legal fees, arising from your use of the interface or the contract, your content, your breach of these terms, or your violation of any law or anyone's rights.

## 16. Release

You release us and everyone involved in publishing the interface from any claim arising from transactions you make with the contract, from the conduct of other users, and from events on any blockchain, stablecoin or third-party service.

## 17. Disputes

17.1 Before bringing any claim, you agree to tell us of it through the **Report this cell** button on the cell's card and to try in good faith, for at least sixty days, to resolve it informally.

17.2 To the fullest extent permitted by law, any claim must be brought individually, never as a plaintiff or class member in a class, collective or representative proceeding, and any right to a jury trial is waived.

17.3 To the fullest extent permitted by law, any claim must be brought within one year after it arose, or it is permanently barred.

## 18. General

18.1 These terms are the whole agreement between you and us about the interface. If any part is held unenforceable, it is enforced to the fullest extent possible and the rest stays in effect. Not enforcing a part is not a waiver of it.

18.2 You may not transfer your rights under these terms; we may transfer ours. We are not liable for any failure caused by events beyond reasonable control, including failures of networks, blockchains, stablecoins, hosting or power.

18.3 Sections 3 to 7 and 9 to 18 survive the end of your use of the interface. These terms are written in English, and the English text controls.

## 19. Changes to these terms

We may change these terms at any time. The date at the top shows the latest version. Using the interface after a change means you accept the changed terms.

## 20. Notices

Notices about content and claims go through the **Report this cell** button on the cell's card.
